Selective disclosure
Reveal only attributes needed for a decision.
Explore privacy engineering as an architecture discipline: data minimisation, selective disclosure, proof systems, trust boundaries and verification cost.
Reveal only attributes needed for a decision.
Evaluate proof systems against performance, setup, security and verification requirements.
Keep personal or commercially sensitive data off shared ledgers where possible.
Define what is checked, against which issuer/policy and with what evidence.
Model correlation, metadata leakage, replay and side-channel risks.
Test proving time, verification time, proof size and operational complexity.
Start with the information you need to prove—not with a proof system.
